performance - KDB+ / Q Syntax optimizations to oneliners -

i definitly q-mortal. q-baby. have question how put code separate lines one-liner. guess there way more elegant solution mine.

1. how write following statements in 1 line:

   q)t1:(3#3)?\:`8 q)t1[;0]:`abc 

2. in table creation, how can add column have list (like command ([]id:id_list;data:data_list;.....)). till creating table , doing inner join on them. guess that's not efficient:

   `id xkey update id:i flip (`row1`row2!(1 2;3 4)) 

for 1st 1 may do:

q)`abc,/:(3#2)?\:`8 abc jognjhck cihanjhp abc hkpblald aeajbddp abc blmjhgah ooeiogdj 

for 2nd 1 may treat table dictionary:

q)tb row1 row2 --------- 1    3    2    4    q)(tb`id): 5 6 q)tb row1 row2 id ------------ 1    3    5  2    4    6
